Anyone with experience changing large tires on semi-trailers, that might have any tips about getting one mounted?
I'm doing this by hand.
I finally have the lugnuts off (33mm on unilug).
But I'm having issues getting the new wheel on the studs and lined up.
It's a real adventure with broken ribs.

Great idea.
I didn't have anything suitable with me today.
I have some three footers around.
Think that will be enough?
I had a bigger one somewhere if I can find it.

Doing okay with the ribs so far, but I don't think I want to wrestle that rim on without some help.
Bar might do it.

I got a 20" breaker from northern tool plus the 33 mm socket in 3/4".
Couldn't afford the three foot breaker, even from them.
Had to use a pipe on the breaker.
One very stubborn nut left that wouldn't come loose, and broke the first socket I tried.
I have a traditional 4-way tire wrench, but Surprise!...it wouldn't fir the newer stuff.
They still make these wrenches, even in metric now, but expensive.

I can't shift it without damaging the tire on the wheel now.
I only have the outer rims on it now, and due to the suspension, I can't move it to where it is going without fixing the tire.
This type of suspension shifts weight to the lower axle, so a flat tire gets all the weight.

will the tire rim hang on the hub? Once its there can you get a bar under the tire to finesse it into place? im trying to imagine doing this in your condition. is there no one to help you for 5 damn mins.......lol

Well, I gathered up all the prybars I could get, including an eight foot long, 1" solid milspec titanium rod, and found two people to help.
While we were unloading, one of the guys, a mechanic of questionable skill (usually), walked over and slid the wheel on.
I didn't see him do it, so I don't know exactly how he did it, and his explanation doesn't help at all.
He says to start with the bottom studs, which I was trying to do.

So either I had everything almost set when I stopped last time, or I really am not getting this at all.
And I wasn't going to pull it off again to practice.

While loading up, I caught on a vine and went into a big hole really hard, just like a cartoon coyote.
I couldn't even land well because I was busy trying to not get sliced up on the big piece of metal I was carrying.

And it was still a pretty good day.

So I guess the lesson is to just rush the right person over next time and let them tip it into place with their forefinger.
